Re: [Guide] Graceful shutdown switch without Pololu

BREAKTHROUGH!!!!! In the battery monitor script: 25. GPIO.setup(powerGPIO, GPIO.IN, pull_up_down=GPIO.PUD_UP) 64. if GPIO.input(powerGPIO) is 0: 87. if GPIO.input(powerGPIO) is 1: In config.txt: dtoverlay=gpio-poweroff,gpiopin=22,active_low="y" Wire it up like this: http://i.imgur.com/Yh17D91.jpg I...

Re: [Guide] Graceful shutdown switch without Pololu

@KrxXxiT All I'll be doing is releasing a modified version of Popcorn's script for each of my shutdown boards. The videos and everything else will remain the same. Still, a modified version will work, the current one doesn't. Man I'm looking forward to this, it's the last part I need to complete my...

Re: [Help Needed] How to wire original DMG Pot. Volume Wheel

Maybe this will help, it's a reference point for the original DMG potentiometer... I refered to this when wiring up mine with the low pass filter and amp. Works fine after increasing the amplification through retropie's audio menu.

Re: [Guide] Graceful shutdown switch without Pololu

Thanks @RxBrad for testing this out. For a moment I thought I was going nuts :roll: I after all this I think the problem lies in @popcorn's script, as it wasn't designed to be used in conjunction with @Camble's circuit. When @Camble releases his script (he referred to it in a previous post) I'm sure...

Re: [Guide] Graceful shutdown switch without Pololu

Since my last post, I've been testing and playing around with different configurations. I've made these diagrams to show what exactly I did. Layout 02 seems to work but with the DMG switch behaving opposite of how it should. I'm thinking to just swap around the wires on the switch to get it to work...

Re: [Guide] Graceful shutdown switch without Pololu

@RxBrad The circuit is exactly the same, just reverse the Drain and Source. From the EN pin on the PowerBoost, you want your switch, then the Fairchild JFET Source. Then the JFET Drain goes to ground instead. Keep the 100K resistor across the Gate/Source and it should work. @myPiZero I'd ditch the ...

Re: [Pre-Order] Safe Shutdown Switch (PowerBoost Version)

I ordered one last night and sent you (@Camble) an email asking if you can assemble it for me.
Wasn't sure where to ask for assembly as I didn't see the option to leave a comment when purchasing.

Re: [Guide] Graceful shutdown switch without Pololu

I think I may have spent $30 on various online orders of parts trying to get this switch alone to work. At this point I feel obligated to get it working. Who has gotten it working besides Camble? :) (If you could post a working Fairchild FET diagram, @Camble, I think a lot of us in the States would...

Re: [Guide] Graceful shutdown switch without Pololu

I got fed up with screwing around trying to get this to work. I tried everything in the guide and nearly broke my screen, I soldered too much and the stuff nearly shorted out something on the other circuit board.
Anyways decided to just order one off you @Camble
